Preface 



This manual is intended as an introduction to the IBM 3210 
Console Printer-Keyboards. The 3210's are described here 
according to the way in which they operate with IBM 
System/370. 

However, because the 3210 Model 2 is a standalone I/O 
unit, the assigned functions of the control keys and indi- 
cator lights described here may vary according to the 
particular requirements of another system. 



Second Edition (December 1970) 

This manual is a major revision of the previous edition that described the 3210 
Model 2 only. This revision includes the 3210 Model 1. 

Changes are continually being made to the information herein; any such changes 
will be reported in subsequent revisions or Technical Newsletters. 

Requests for copies of IBM publications should be made to your IBM representative 
or to the IBM branch office serving your locality. 

This manual has been prepared by the IBM Systems Development Division, Product 
Publications, Dept. 171, P.O. Box 6, Endicott, N.Y. 13760. A form is provided at 
the back of this publication for readers' comments. If the form has been removed, 
comments may be sent to this address.

IBM 3210 Console Printer-Keyboards 



The 3210 Console Printer-Keyboards are auxiliary I/O 
terminal units that provide two-way communication between 
the operator and an attached data processing system. This 
communication is in the form of keyboard entry and printed 
output. 

The 3210 printer-keyboard consists of the new Selectric® 
I/O-II printer keyboard mounted in an operator's console. 
Intended for use with IBM System/370, the 3210 is avail- 
able in two models-one local, and one remote-that have 
the same capabilities except for alter/display. 



MODEL 1 

This model (Figure 1) is mounted on a table attached to 
the System CPU. It has the capability of altering or dis- 
playing data in storage. 



MODEL 2 

This model (Figure 2) is mounted on a pedestal and is 
attached to the CPU by an external signal cable. It has its 
own ac line cord and no alter/display capability. Accordingly, 
the Model 2 has no alter/display light or key (see Control 



Keys and Indicator Lights). In the positions occupied by 
this light and key on the Model 1 , the Model 2 has an ac 
power-on and an ac power-off switch. It also has its own 
ac power control system built into the pedestal. 



PRINTER 

The printer uses a 15-in. (381 mm) carriage with a pin-feed 
platen that accommodates marginally punched forms 
having a hole-to-hole width of 13-1/8 in. (333,4 mm). 
This carriage handles a maximum of one original and five 
carbon copies of pin-feed forms. For best results, however, 
no more than three carbon copies are recommended. 
Vertical line spacing is six lines to the inch (25,5 mm); 
horizontal spacing is ten characters to the inch. 

The printer has fixed margins and no tab or backspace 
capabilities. It uses the standard Selectric® cartridge 
fabric ribbon and has no pressure rolls or paper bail. It 
uses a special print element having an arrangement of the 
88 printable characters designed (Figure 3) to provide 
maximum throughput and fast response when keying. 

Printer functions are print, space, and new line (carrier 
return accompanied by a line feed). Print and space

operations take place at speeds of 15.5 characters per 
second; carrier return speed is about 15 inches (381 mm) 
per second. 

For additional information on forms specifications, refer 
to Form-Design Considerations-System Printers, GA24-3488. 

For additional information on 3210 operating procedures, 
refer to IBM System/ 370 Model 145 Operating Procedures, 
GA24-3554. 



KEYBOARD 

The keyboard (Figure 4) has 44 operating character keys 
that can transmit 88 encoded characters to the attached 
system. The tab and backspace keys, although present, 
are blank and inoperable. The shift, lock, and return keys 
are standard, as is the space bar. The keyboard has no 
typamatic (continuously repetitive) keys. 



CONTROL KEYS AND INDICATOR LIGHTS 

Figure 5 shows the operator control keys and indicator 
lights that flank the 3210 keyboard. Depending on the 
model, the two lower left positions are either alter/ display 
lights and switches, or power on/off switches, as indi- 
cated in the drawing. No associated logic is furnished 
with the 3210 printer4ceyboards. Any logical function 
performed as a result of key operation is a function of the 
user attachment. The functions assigned the control 
keys and lights in this manual are those used by the 3210 
with the IBM System/370. Conceivably, other users might 
assign them other functions.

Function 

Resets the alarm indicator. 

On the Model 1 only, causes the attachment 
to service the manual alter or display operations. 
Note: The CPU stop key must be pressed 
before the alter/display key can be used. 

Terminates a read operation only. 

Terminates a read, write, or store operation. 

Makes the printer-keyboard not ready and 
puts it in an offline condition. 

On the Model 2 only, is in the position 
occupied by the alter/display key on the 
Model 1. It removes ac power from the 
printer drive motor. 

On the Model 2 only, is in the position 
occupied by the alter/display mode light on 
the Model 1. It turns on ac power to the 
printer drive motor. When ac power is on, 
the label on this key is illuminated. 

Places the printer in a ready state after forms 
have been correctly positioned and the top 
cover closed. 

Signals the attachment that the operator 
desires to enter data from the keyboard. 



Indicator Lights 

These incandescent bulbs, when lit, shine through their 
translucent plastic lenses to illuminate the engraved labels.

(Intervention

Function 

Indicates that an alarm command was issued 
by the attached system. On the 3210 printer 
keyboard, the alarm consists of this visual 
indicator only. The actual alarm is an audio- 
tone emitting device in the CPU. 

Indicates that the printer-keyboard attach- 
ment is in a status in which it can perform 
manual alter or display operations. 

Indicates that some condition exists that 
requires operator attention, such as forms 
runout, cover open, (or ac power off on the 
Model 2). 



Light Function 

Power On On the Model 2 only, is part of the power-on 

switch (key). It lights whenever the operation 
of the power-on key has turned on ac power 
to the printer. The light remains on until the 
ac power is shut off. 

Proceed Indicates that the system is ready to accept 

data from the keyboard. 

Request Pending Indicates that a request key operation has 
been initiated but that the system is not yet 
ready to accept data from the keyboard. 



Cover Interlock Switch 

The 3210 printer-keyboards are equipped with a cover 
interlock switch that signals the system that operator 
intervention is required to close the cover. 



PAPER-HANDLING FACILITIES 

The Model 1 has two shelves at the back to hold paper forms. 
The supply of blank forms is placed on the lower shelf. The 
paper then is threaded through a slot in the upper shelf and 
inserted through an opening at the top of the printer where 
the marginal perforations can engage the platen feed pins. 
As printing progresses and the forms advance through the 
printer, they emerge through the same opening by which 
they entered and are stacked on the upper shelf. 

The Model 2 has only a single (stacking) shelf that holds 
the printed forms as they emerge from the printer. The 
supply of blank forms is placed on the base of the machine 
(refer to Figure 2), and the paper is threaded through the 
slot in the stacking shelf and inserted in the printer in the 
same manner as for the Model 1 . 

Forms length is limited by the shelf size to 1 1 inches 
(279,4 mm). 



MACHINE POWER 

The Model 1 derives all its power, both ac and dc, from 
the attachment circuitry in the CPU. 

The Model 2, however, has a power-on switch and line 
cord that provide the ac power to the drive motor in the 
printer. All other (dc) power and signal lines must be 
supplied by the attached system through the printer- 
keyboard interface connectors and the external 
connecting-cable provided with this model.
